I have pretty strong, wood, built in shelving in large portion of my downstairs living area. Normally, one would put pictures, or other decor to show on the shelves. I use the space to put my canning. They are filled top and bottom, and closed cabinets on the bottom row, which are pretty deep. Shelves are holding up well. Something I have thought is when we have company (which is rare), everyone can see a lot of the canned food. It sort of fits a "farmhouse" decor, but probably not a good idea for all to see the food one has stocked up. I also have it stashed on wooden bookshelves in laundry room, portable metal shelving tucked back in nooks n cranny areas out of they way. I put a window air unit in an outside building with intent to relocate everything out there, but that ended up getting stuffed with large file cabinets, supplies like TP, paper towels, medical supplies, and other miscellaneous supplies, including my empty canning jars n lids.
Running out of room!
